Abstract Author Manuscript

Objective—To synthesize qualitative evidence on linkage to care interventions for people living with HIV. Design—Systematic literature review. Methods—We searched nineteen databases for studies reporting qualitative evidence on linkage interventions. Data extraction and thematic analysis were used to synthesize findings. Quality was assessed using the CASP tool and certainty of evidence was evaluated using the CERQual approach.

Author Manuscript

Results—Twenty-five studies from eleven countries focused on adults (24 studies), adolescents (8 studies), and pregnant women (4 studies). Facilitators included community-level factors (i.e. task-shifting, mobile outreach, integrated HIV and primary services, supportive cessation programs for substance users, active referrals, and dedicated case management teams) and individual-level factors (encouragement of peers/family and positive interactions with healthcare providers in transitioning into care). One key barrier for people living with HIV was perceived inability of providers to ensure confidentiality as part of linkage to care interventions. Providers reported difficulties navigating procedures across disparate facilities and having limited resources for linkage to care interventions. Conclusions—Our findings extend the literature by highlighting the importance of task-shifting, mobile outreach, and integrated HIV and primary services. Both community and individual level

Introduction

Author Manuscript

HIV is a global public health threat and a comprehensive response demands coordinated action. The results of the HPTN 052 trial [1, 2] suggest that universal testing and treatment may increase the number of people living with HIV (PLHIV) who achieve viral suppression, preventing onward transmission. However, this benefit is contingent on PLHIV being retained throughout the care continuum, including linkage to care. We define linkage to care as confirmation of HIV diagnosis and first HIV-specific clinical visit [3, 4]. Recent studies demonstrate the importance of early linkage to care and therapy initiation [5–9]. Early linkage to care may decrease HIV-associated morbidity and mortality [10, 11]. Most evaluations of linkage to care interventions have focused on quantitative assessment [5]. Although large quantitative studies have been conducted in many settings, there are many questions that quantitative methods cannot adequately address [12–16]. Qualitative research can more effectively elucidate the local factors impacting linkage to care for individuals. Social and behavioral factors are known to play a large role in the effectiveness of HIV interventions [17] and qualitative evaluations are increasingly integrated into interventions focused on promoting linkage to care [5, 18–21].

Author Manuscript

Qualitative meta-synthesis is useful in evaluating interventions for several reasons [13, 16, 22]: 1) It facilitates understanding of the mechanism of the intervention; 2) it examines acceptability and feasibility directly related to implementation; 3) it helps identify intervention adjustments to optimize impact. Our review builds on these advantages by synthesizing qualitative evidence on PLHIV and their care providers to identify facilitators and barriers to linkage to care interventions.

Methods

Author Manuscript

We conducted a systematic review of qualitative evidence of linkage to care for individuals testing positive for HIV. Following Cochrane guidelines, we conducted a comprehensive search strategy (Supplemental Table 1) to identify all relevant studies regardless of language or publication status publically available without prior date restrictions on Feb 21 2015. We developed this strategy in accordance with PRISMA guidelines and registered our study in PROSPERO (CRD42015017252). An important step in our strategy was devising a broad list search terms to encompass the scope of relevant HIV linkage to care intervention research (Supplement Table 1). We queried search terms in nineteen journal and thesis databases: CENTRAL (Cochrane Central Register of Controlled Trials), EMBASE, LILACS, PsycINFO, PubMed (MEDLINE), Web of Science/Web of Social Science, CINAHL, British Nursing Index and Archive, Social Science Citation Index, AMED (Allied and Complementary Medicine Database), DAI (Dissertation Abstracts International), EPPIAIDS.

Centre (Evidence for Policy and Practice Information and Coordinating Centre), ESRC (Economic and Social Research Council), Global Health (EBSCO), Anthrosource, and JSTOR. We then checked for abstracts from Conferences on Retroviruses and Opportunistic Infections (CROI), International AIDS Conference (IAC), and alternating years of International AIDS Society (IAS) clinical meetings from their inception dates (1993, 1985 and 2001, respectively). We also contacted researchers and relevant organizations and reviewed references from all included studies. Study inclusion criteria

Author Manuscript

Our goal was to evaluate studies that used qualitative methodology and analysis to examine interventions with an aim to improve HIV linkage to care. Intervention designs included research aimed to accelerate initiation of HIV-specific medical services and/or enhancing multiple steps within the care continuum. We identified all relevant studies from low, middle, and high-income countries. Qualitative methodologies included ethnographic research, case studies, and process evaluations. Qualitative analysis included framework analysis, thematic analysis, and content analysis. Studies using mixed methods were included if qualitative methods and findings could be extracted and analyzed. Exclusions Studies were excluded if they met any of the following criteria: did not report an intervention, did not examine linkage to care, did not focus on PLHIV, was comprised of only a literature review, did not use or report qualitative data. Studies that solely used quantitative methods to investigate interventions for HIV linkage were excluded, as were mixed studies that only reported on quantitative findings.

Author Manuscript

Assessment of the quality of included studies Once relevant studies were identified, we conducted a quality assessment using a sevenquestion measure adapted from the CASP tool [23]. We chose this measurement because it has been used in similar studies [24, 25]. This tool evaluates study context, researcher reflexivity, sampling methods, the appropriateness of data collection methods, analysis techniques, and sufficiency of qualitative evidence (Supplement Table 2). We then used the SPICE model to review a study’s setting, perspective, intervention, comparison, and evaluation (Supplement Table 3). The SPICE model frames the systematic review question and is analogous to the PICO (population, intervention, comparison, and evaluation) model used in quantitative systematic reviews[28, 29]. Assessment of the certainty of evidence of qualitative studies

Author Manuscript

We used the CERQual approach to assess the methodological limitations, coherence, relevance, and adequacy of our review findings [27, 30]. CERQual is a tool analogous to GRADE for evaluating the confidence of review findings in qualitative systematic reviews [27, 31]. CERQual confidence levels were assigned based on an overall assessment of four scores from composite studies: methodological concern, coherence, relevance, and adequacy. Themes from studies assessed as having only minor methodological concern and high coherence, relevancy, and adequacy accordingly received high CERQual confidence.

Themes from studies with major methodological concerns and low relevance or coherence scores were assigned low CERQual confidence. Themes from studies that received mixed scores across the four criteria were assigned moderate confidence. Data extraction and synthesis for emergent themes

Author Manuscript

We used a framework thematic synthesis approach based on the theory of conceptual saturation [32, 33]. Thematic synthesis is one of the approaches [33–36] recommended by the Cochrane Qualitative Review Methods Group [31]. Data extraction was applied to primary (source data) and secondary (main findings, interpretation of data) information from original qualitative research exploring the experiences and attitudes of stakeholders towards HIV linkage interventions. We extracted the following data from reviewed studies: country of study, rural/urban locality, linkage to care definition, qualitative data types, primary data findings, elements from the CASP tool, acceptability/feasibility issues, and main findings addressed in discussion or conclusion sections. Two coders (LT, JB) examined a subset of the selected literature to harmonize data extraction. All studies were independently coded by one individual and cross-checked by a second individual. Emergent themes were identified from studies by reviewing primary and secondary data. We reviewed the data for common themes. Subanalyses among key populations, adults, adolescents, children, and pregnant women were undertaken where sufficient data was available.

Results

Author Manuscript Author Manuscript

From 9136 citations, 678 abstracts were assessed for studies reporting qualitative data on linkage to care interventions (Table 1). The abstract review yielded 178 citations for a fulltext review (Table 1). Of these, 175 manuscripts were excluded because they did not report on intervention (72), did not examine linkage to care (48), did not report qualitative finding (26), did not focus on PLHIV (5), or were reporting on literature reviews (2) (Table 1). We identified twenty-five manuscripts comprised of twenty-two peer-reviewed articles [18, 19, 21, 37–55], two theses/dissertations [56, 57] and one conference abstract [58] (Figure 1). Among these, seventeen studies were single component interventions [19, 21, 37–42, 45, 47, 49, 50, 53, 54, 56–58] and eight were multiple component interventions [18, 43, 44, 46, 48, 51, 52, 55]. We identified cross-sectional (16) [18, 19, 39, 41–46, 49–51, 53–55, 58], longitudinal (6) [21, 37, 47, 48, 52, 57], and longitudinal-quantitative parent studies (3) study designs [38, 40, 56]. Twelve studies [18, 37–41, 44, 47, 49–51, 53] were from highincome countries (HIC: USA, UK, Canada), eight [19, 43, 45, 46, 52, 54, 56, 58] from middle-income countries (MIC: South Africa, India, Botswana), and five [21, 42, 48, 55, 57] from low-income countries (LIC: Haiti, Tanzania, Cambodia, Malawi, Kenya). Overall, 24 studies focused on adults [18, 19, 21, 37–43, 45–58], eight included adolescents (defined as ages 10–19) [21, 37, 44–48, 57], and four included pregnant women [21, 43, 55, 57]. None included children. We identified five intervention-specific themes and ten cross-cutting themes (Table 1).

Intervention Specific Themes Task-Shifting (Four studies, CERQual high confidence)

Author Manuscript

Task-shifting was identified as effective in increasing linkage to care among PLHIV in four studies [42, 43, 45, 54]. The four studies were from Botswana, Haiti, and South Africa. Task-shifting interventions entailed any “process whereby specific tasks are moved, where appropriate, to health workers with shorter training and fewer qualifications [59],” particularly in low- and middle-income country (LMIC) settings affected by human resource shortages [60]. Task-shifting increased the range of responsibilities of community health workers, and improved linkage to care by increasing HIV knowledge in the community. This increased knowledge reduced HIV-related stigma and improved family support, both of which also facilitated linkage to care. Unfortunately, without clear administrative plans for implementation, task-shifting placed an increased burden on healthcare providers [42, 57]. Discussion with healthcare providers elaborated on how task-shifting hindered HIV work, mainly due to additional clinical/administrative burden [54]. Difficulties were exacerbated for non-HIV specialized nurses in task-shifting environments because they were not trained to provide HIV-integrated care [52, 54]. This trend was particularly salient for providers in reproductive health and staff who worked with youth populations [42, 52]. Community-based mobile outreach testing and linkage (Three studies, CERQual high confidence)

Author Manuscript

Community mobile outreach testing and linkage interventions facilitated linkage to care [19, 45, 58]. These three studies were from Botswana and South Africa. This intervention program involved implementing home-based testing and counseling [45, 58] and workplacebased voluntary testing and counseling intervention in rural/mining areas [19], with subsequent linkage to care at community health centers or on-site health services at rural worksites. Community-based programs were reported as acceptable to both PLHIV and healthcare providers as useful for improving linkage. Integration of HIV-specific and primary medical care (Two studies, CERQual moderate confidence)

Author Manuscript

Two studies examined interventions targeting systematic, institutional coordination and integration of specialized HIV care into primary care services. These two studies were from South African and the United States. The intervention aimed to reduce costs, appointment wait times, and the total number of medical clinics necessary for linkage to care. Two studies reported that integration of HIV care into primary care services was acceptable and feasible to PLHIV and health providers. These studies identified several factors (administrative barriers, provider preferences, and patient preferences for having a dedicated HIV provider) that warrant further consideration in integration. Provider Initiated Testing, Counseling (PITC), and Linkage (Two studies, CERQual low confidence) PITC and linkage to care facilitated improvements in linkage to care. These two studies were from Kenya and Malawi. This intervention had healthcare providers at non HIV-specific

medical centers initiate HIV testing for clients who originally scheduled medical visits for other services. One study based in pregnancy- services centers intervened by administering a qualitative survey to determine best supports (presence of social support, interactions with healthcare workers, and reduced health services costs) for linkage to care [21]. Another study evaluated two interventions using a community-based cluster randomized trial of a facility-based initiated HIV care compared to home initiation of HIV care after home selftesting [57]. These studies [21, 57] showed that PITC-linkage improved linkage to care for PLHIV, and indicated challenges in scaling-up of interventions beyond individual facilities. Cessation support for people who use drugs to prepare for HIV linkage (Two studies, CERQual high confidence)

Author Manuscript

The impact of providing cessation support for PLHIV who use drugs as enrollment preparation was effective in facilitating linkage programs [44, 49]. These studies were from the United States. These programs targeted less-studied, marginalized populations of individuals recently released from jail [49] and young adults [50]. The main finding was that substance use cessation support is vital and a necessary precursor before effective linkage to care implementation.

Cross Cutting Themes Diverse provider feedback for intervention implementation, facilitators, and barriers (Ten studies, CERQual high confidence) Ten studies reported on providers’ experiences with linkage to care interventions [18, 38, 41–43, 46, 51, 54, 55, 57]. These studies were from the United States, England, Haiti, South

Author Manuscript

Africa, Malawi, and Cambodia. This theme focused on synthesizing the experiences providers encountered in implementing diverse interventions across HIC and LMIC for general and key HIV populations. Three subthemes emerged, each focused on processes of implementation, facilitators for successful intervention, and barriers inhibiting linkage interventions for PLHIV. Subtheme: intervention implementation processes (Ten studies, CERQual: high confidence) Ten studies reported feedback about implementation processes [18, 38, 41–43, 46, 51, 54, 55, 57]. Providers discussed how successful implementation of linkage interventions required greater clarity in coordinating referrals for PLHIV between health centers.

Author Manuscript

Subtheme: intervention facilitators (Seven studies, CERQual high confidence) Seven studies reported on intervention facilitators [18, 38, 41–43, 51, 55]. Healthcare providers reported that having guidance protocols for integrated services simplified navigation of medical systems on behalf of PLHIV. Guidance protocols also helped improve patient-physician trust and PLHIV knowledge about referral patterns [18, 38, 41–43, 51, 55].

Subtheme: barriers to interventions (Six studies, CERQual high confidence)

Author Manuscript

Six studies identified barriers to successful implementation of linkage to care interventions [18, 38, 46, 54, 55, 57]. Providers discussed how lack of dedicated staff and staff shortages hindered implementation. Studies also reported the need to integrate volunteers into existing tasks carried out by employees at medical facilities. Current WHO staging guidelines complicated integration at local levels because fulfillment of and compliance to guidelines required resources not available at all clinics [57]. Providers reported experiencing high workload, feeling like they were gatekeepers in selecting which patients would be subjectively chosen to receive treatment. Confidentiality concerns among PLHIV (Five studies, CERQual moderate confidence)

Author Manuscript

Confidentiality concerns of PLHIV adversely influenced the effectiveness of linkage interventions [19, 43, 45, 52, 58]. These studies were from South Africa, India, and Botswana. PLHIV who initially participated in several HIV testing interventions (workplace testing, home based testing service, multiple-service or one-stop HIV care centers, and VCT testing) withdrew from subsequent linkage to care interventions because they lived near the intervention facility and feared unintended serostatus disclosure to their local community. Referral systems (Twelve studies, CERQual high confidence) Twelve studies reported on active referral systems [18, 21, 38–41, 44, 45, 48, 49, 51, 57],

Author Manuscript

defined as provider assistance for PLHIV in scheduling appointments for medical follow-up and related services (taxi vouchers, enrollment in public health insurance, references to mental health, housing, food assistance services) after a positive HIV test. These studies were from the United States, Tanzania, England, Kenya, Botswana, and Malawi. Active referral systems and processes were effective in linking PLHIV into the care cascade, with active referrals being preferred over non-active or no referrals. Non-active referrals included tester receiving HIV literature or phone numbers for HIV center, or being informed they should make an appointment for further care with no direct assistance from a counselor. Active referral systems were feasible and acceptable to health providers and PLHIV, particularly for youths, women, and the homeless. Case management and support teams for coordinating linkage to care services (Eight studies, CERQual moderate confidence)

Author Manuscript

Case management and support teams for coordinating linkage to care services facilitated successful linkage [39–41, 44, 49–51, 53]. Seven were from the United States and one was from Canada. This theme focused on comprehensive interventions where HIV-infected individuals had access to case managers who coordinated counseling testing, referral, and designated linkage provider teams. All eight studies were from HIC, and all reported that PLHIV and health care providers found the intervention acceptable. Persistent pre-post intervention issues regarding anxiety, fear, and misinformation of HIV (Nine studies, CERQual moderate confidence) Persistent issues present prior to and after linkage interventions hindered linkage to care initiatives [19, 21, 37, 40, 43, 45, 50, 55, 58]. These studies were from the South Africa,

Author Manuscript

Kenya, United States, Canada, Cambodia, and Botswana. Persistent issues were defined as a lack of knowledge, awareness, or misinformation about HIV and the anxiety and fear of stigma linked to confirmation of HIV-positive status. These issues were most evident as reasons provided for not attending follow-up among pregnant women and youth. Family and peer support (Ten studies, CERQual moderate confidence)

Author Manuscript

Ten studies evaluated the importance of support from close family members, friends, and peers from within one’s community as facilitating interventions by encouraging PLHIV to enter HIV specialized care [19, 21, 43, 45–47, 50, 55, 57, 58]. These studies were from South Africa, India, Kenya, Botswana, Malawi, United States, Canada, and Cambodia. Studies reported on how family involvement assisted care providers in contacting and enrolling PLHIV, particularly pregnant women, into linkage to care for HIV primary care [19, 21, 43, 45–47, 50, 55, 57, 58]. Another component of involvement centered on concerns about disclosure, distrust and conflict with close contacts such as partners, family and friends before HIV diagnosis. Importance of positive interactions with health workers and case managers (Twelve studies, CERQual high confidence)

Author Manuscript

Twelve studies assessed how healthcare providers and support workers living with HIV and advocating on behalf of PLHIV improved linkage interventions [21, 38, 41, 44, 46, 49, 51– 53, 56–58]. These studies were from the United States, India, England, Kenya, South Africa and Malawi. Reports emphasized the importance of perceptions among PLHIV towards providers, stressing the positive impact of having trusting relationships with providers. Negative interactions correlated with less effective linkage because PLHIV were less motivated to return for test results, hindering progression onto assistance in linking to HIV services. Our findings extend the literature by highlighting the importance of task-shifting, mobile outreach, and integrated HIV and primary services. Both community and individual level factors may increase the feasibility and acceptability of HIV linkage to care interventions.

Discussion We found a number of linkage to care interventions that were feasible and acceptable in low, middle, and high-income country contexts. This review expands the literature by including a formal assessment of qualitative literature [27, 60, 61], assessing potential harms of interventions, and examining human rights implications of interventions [62, 63].

Author Manuscript

We found that task shifting interventions improved linkage to care. This is consistent with a quantitative review [17] and existing WHO guidance on task shifting [42, 43, 45, 54]. Community health workers noted the importance of adequate training and institutional support to servicing diversified populations of PLHIV, including pregnant women, adolescents, teens, and other minorities to deliver linkage interventions [42–44, 52, 54, 55]. The relative low cost and limited harms associated with this type of intervention across many settings suggest that it could be scaled up in a variety of low and middle-income countries. AIDS.

We found that community-based mobile outreach testing and linkage programs enhanced linkage to care [19, 45, 58]. These interventions decreased the travel barriers that often prevent prompt linkage to care [15, 40, 53]. Mobile outreach services also helped to reduce stigma associated with accessing HIV services [15, 40, 53]. We found that integrating HIV and primary care services was feasible and acceptable in a many settings in high-income countries. This finding is consistent with a small quantitative literature on HIV and primary care integration [64, 65] and found effective in high income settings [66, 67]. Several themes supported this finding (cessation support services for substance users, active referrals, and case management team counseling), highlighting the many ways in which integration could be effectively implemented [14, 17, 33–36, 39, 40, 43, 44–46, 48, 52]. Health care providers supported integrated service models because of improved navigation in coordinated team settings across several health facilities.

Author Manuscript

Several limitations should be considered in the interpretation of these findings. First, we did not identify any linkage to care interventions specifically focused on men who are known to have poor linkage [68–70]. This has been noted in the quantitative literature as well and underlines the need for greater programs focused on serving men. Second, all data was cross-sectional. The lack of multiple observations introduces recall bias and limits the inferences that can be made about changes over time.

Author Manuscript

Our study has several research implications. First, task shifting holds great promise as a scalable intervention to promote linkage to care in low, middle, and high-income countries. Given that task shifting has not been widely implemented in locations with poor linkage to care [60, 61, 66], implementation research on how best to facilitate task shifting is needed, especially in settings with poor linkage to care. Second, research on linkage to care among women, adolescents, and children should be a priority given their under-representation in linkage to care research [3, 5, 63, 65–67]. Third, as task shifting expands HIV service delivery into a wider range of settings, research on maintaining confidentiality and privacy will be important. PLHIV and health providers both identified that a lack of training in task shifting and confidentiality practices are major barriers in successful linkage to care programs [19, 21, 37, 40, 43, 45, 50, 55, 58]. HIV linkage to care interventions will be increasingly important in order to achieve the UNAIDS 90–90–90 as larger numbers of individuals receive testing and enter the continuum of care. Our review findings provide a number of policy-relevant suggestions for the design and implementation of linkage to care programs.

(1) DIVERSE PROVIDER FEEDBACK reports on providers and lay healthcare workers experiences in carryingout diverse intervention implementation. Feedback was generally positive, with many interventions reported as acceptable for providers and care workers. Three subthemes emerged from analysis of linkage to care for PLHIV: implementation process, facilitators, and barriers (2) IMPLEMENTATION PROCESS: providers discussed how successful implementation of linkage to care on their part required greater clarity in coordinating the referral process across centers to improve the quality of references to other providers. At the institutional level, developing a focus on client-centered care, and devising plans to work as an administrative team for getting PLHIV linked into care were essential for successful linkage programs (3) FACILITATORS: providers reported that having guidance protocols for integrated services simplified assistance in navigating complex medical system(s) for PLHIV. Simplification enabled improvement in perceptions of

Author Manuscript (4) BARRIERS TO INTERVENTIONS: need to calibrate different procedures and cultures across institutions to improve linkage to care. Lack of dedicated staff and staff shortages hindered implementation for providers. Need to integrate volunteers into existing tasks carried out by employees at medical facilities. Current WHO staging guidelines complicated integration at local levels because fulfillment and compliance to guidelines required resources not available at all clinics. Providers experienced high workload, often felt like they were gatekeepers in offering care to PLHIV as they had to subjectively choose which individuals would receive treatment. Medical professionals also discussed how task-shifting for staff can hinder HIV work – primarily, additional clinical/administrative burden for non-HIV specialized nurses in task-shifting environments were not trained to provide HIVintegrated care, so they are trained to perform care and hence uncomfortable/unwilling to do so (esp. reproductive health and youth)

PLHIV for trust and knowledge of referrals. Task-shifting of care from doctors to nurses increased the range of responsibilities of CHW, thereby improving linkage to care because of elevated levels of HIV knowledge in community-wide setting. Increases in community knowledge further improved linkage to care by reducing stigma and improving family support Anaya 2015; Cameron 2009; Lazarus 2012; Macpherson 2013; Uebel 2013; White 2013

(5) CONFIDENTIALY ISSUES: participants of interventions such as workplace testing, home based testing service, comprehensive HIV centers, and VCT testing all had reported concerns about confidentiality (6) REFERRALS: Active referrals preferable to non-active or no referrals: Active referrals included interventions where PLHIV particularly youths, women, and homeless, receive assistance in scheduling appointments for medical follow-up and related services (taxi vouchers, help navigating and getting enrolled in public health insurance, mental health, housing, food assistance services) after a positive HIVtest. These activities improved linkage. Non-active referrals included tester receiving HIV literature or phone numbers for HIV center, or being informed they should make an appointment for further care with no direct assistance from counselor/HIV test administrator (7) CASE MANAGEMENT and SUPPORT TEAMS FOR COORDINATED LINKAGE TO-CARE SERVICES: positive impact of having counseling and referrals, particularly in a concerted way, either from a case manager, or a multi-service one-stop center.

Equity & human rights considerations

likely reduced control of confidentiality, increased risk of unintended disclosure at home and work place, with increased likelihood of distress and conflict within household of PLHIV reduces acceptability

some resistance by health care workers due to stigma of HIV because of inadequate training and sensitivity to complementary health and discrimination issues •

Relevant papers

increased risk of unintended disclosure and potential reduced control of confidentiality health facilities both reduce acceptability for PLHIV

health care providers may prefer current procedures and treatment methods , and may encounter administrative barriers, or face institutional differences in integration •



may reduce incentives to seek HIV care for PLHIV who prefer more discretion in HIV treatment services, and for PLHIV who prefer to continue care with existing providers •
